America’s latest sixth-generation nuclear stealth bomber made its debut on December 2 after years of secret development. The B-21 boasts a futuristic flying-wing design and is intended to fly thousands of miles to strike targets deep behind enemy lines. Northrop Grumman said the Raider “will provide the US Air Force with long range, high survivability and mission payload flexibility”. For years, the US Air Force (USAF) has kept details about its new bomber tightly under wraps. Despite the unveiling, the USAF and Northrop Grumman officials offered no new information about its capabilities. Will the B-21 Raider help America regain air superiority?
